Video: Getting Started With Minimum Quantity Lubrication
Minimum quantity lubrication does not require a special machine tool or special tooling. This video makes the case for MQL and describes how to apply it effectively.
Minimum quantity lubrication, or near-dry machining, does not require a special machine tool or special tooling. Technology is available for applying MQL effectively on an existing machining center.
In this instructional video, MMS Online video contributor Todd Schuett makes the case for MQL, and also describes how to apply it effectively.
The recipe for best results is simple: Start with a rigid machine, add a high pressure through-the-spindle coolant system, then combine these with the right drill geometry plus the right speeds and feeds.
The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.
Accuracy is not just inherent to the machine—it also depends on how the machine is used. Try these techniques to let a new or existing CNC machining center achieve its potential precision.
